CRANK-CASE REINFORCEMENT 0R REPAIR ARM.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed July 29, 1918, Serial No. 247,272. Renewed January 13, 1920'. SerialNo. 351,254.

To all whom it may concern:

Be it known that I, ANTHONY G. J AOKSON,

a citizen of the United States, residing at,

Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Grank- Case Reinforcements or Repair Arms, and do hereby declare the following to be a full, clear, and exact description of engines of different types, such as the Ford,

Hudson, etc., and consists of asimple and efiicient device which may be applied without the use of special tools, welding or brazing, etc., and which may be easily and quickly attached without the necessity of sending the engine to a factory, where special tools are required, as is the custom with repair arms now commonly constructed.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings which, with the letters of reference marked thereon, form a part of this application and in which:

Figure l is a vertical sectional view, showing the application of my invention to the crank case of an engine of the Ford type, and

Fig. 2 is a detailed perspective view of the crank repair arm.

Reference now being had to the details of the drawings by letter:

A designates the crank case of an engine, having a laterally extending portion B, and C is a'block over which an angled portion D of the lateral projection of the crank case bears. Angled plates E are bolted, or otherwise fastened, to the block C, and are provided with upright inclined portions F which are riveted, or otherwise securel fastened to the angle plate H, the wing If of which is adapted to rest upon the horizontal flange K of the chassis K. The inclined portion of said angle plate has an upright arm P, which is 'riveted,'or otherwise secured, to the inclined portion of the angle plate H and is provided with an aperture R through which a bolt passes and which bolt also passes through the apertured portion of the chassis and-forming means for securely holding thecangle plateto the'latter. The upper end of the arm P, it will be noted, bears against the upper horizontal flanged portion of the chassis. The lower ends of the plates D are apertured as at T to receive bolts or screws which are passed through the same and the block C upon which the crank case of the engine rests.

'By the provision of a repair armcmade in accordance with my invention, it will be noted that a convenient means is provided for repairing engines and trucks of different kinds and one which may be easily and quickly adapted to the crank case of a chassis, without the necessity of welding or brazing, but simply by the employment of bolts, and at a minimum of time and labor.

By way of illustration, repair of a Ford car by my improvements will be described. In the Ford car the bracket which supports the crank caseA from the chassis frame K, is riveted to the crank case below the flanges thereof and has an upwardly extending arm passing between the flanges B and the chassis frame, such arm having at its top a lateral extension which rests upon the top leg of the chassis frame and is secured thereto. This bracket usually breaks in the arm portion thereof at a point adjacent the flanges. In making the repair the upper portion of the bracket secured to the chassis frame is removed and my improved bracket substituted therefor, this being possible. by reason of the fact that the arms F are spaced apart so as to straddle the remaining portion of the original bracket which is riveted aline with the bolt holes in the flanges B of the crank case which receive the bolts securing the halves of the crank case together. The angle H supports the crank case against downward movement and the plate P and the bolt passing through aperture R support the parts against upward movement and against lateral displacement relative to the" frame.

In using my bracket as a reinforcement; 2'. e., before the original bracket has broken, I remove the bolts which fasten the bracket -to the crank case. The arms F are spaced at such a distance that the apertures T will to the chassis frame, slip my improved bracket in position with the arms F, straddle the original bracket 'an' dthen bolt both the original bracket and; the reinforcement bracket in place. One of the particular a df vantages 0t myv invention is that by my construction of bracket 'engagingthe' inner portions. of the Chassis frame -I-jam1 enabled to use the same bracket either asarepair or as a reinforcement 'iiI-here'as in analogous de-i I necessary ktol use one vices in. the art, I it- 11 7; style of bracket for a reinforcement and airother style otbra'c'ket fora repair.
